I created a client library to send emails for a webapp. After connecting to the SMTP server with credential setup in CPANEL, and then do NOT add Message-Id header, the DKIM signature 'h' record created by dovecot/WHM is wrong, and a Message-ID (with a capital D) header is added, invalidating the generated DKIM signature value. This causes outlook, yahoo, gmail and other email

I created a client library to send emails for a webapp. When the client library makes a connection to the SMTP server, and then do NOT add Message-Id header, Message-ID (with a capital D) header is added, and the SMTP server adds a incorrect DKIM-Signature record 'h' part, invalidating the generated DKIM signature value. This causes outlook, yahoo, gmail and other email recipients

Hi Dear Community Friends, it is few days now, i am trying to figure out why DKIM is working / not working. Any assistance would be very much appreciable. Server IP is not blacklisted ever, MX, PTR SPF, DKIM records are available in DNS. why it is working at Gmail, why failing at Yahoo? Gmail dkim=pass header.i=@digital-infotech.net Yahoo: domainkeys=neutral (no sig);

Hi List Subscribers, In recent months we have been seeing an increasing number of bounced deliveries from libvirt mailing lists[1] due to DMARC policies on list subscriber's mail servers. IOW, many subscribers are only receiving a subset of mails sent to the libvirt mailing lists. We believe the root cause of many of the problems is that mailman is modifying the mail subject to add the

I am trying to install dkim-milter-2.7.2 on a Centos 5.2 system and keep getting the following errors. I have very little experience in C programing so I am at a loss as how to proceed. I have sendmail-devel installed Here is the tail of the result output of sh ./Build make[2]: cc: Command not found make[2]: *** [assert.o] Error 127 make[2]: Leaving directory

Hello mail admin, Currently the nut-upsdev mailing list mail is mostly getting marked as SPAM (or SPOOF) due to failed DKIM. DKIM is trying to verify mail headers signed by the original sender, but using the mailing list DKIM key (or lack thereof). This occurs because the DKIM mail authentication looks for a authentication key for the headers based on the HELO/ELHO user, but the message is DKIM

Hello again, I noticed mails from the Dovecot list break DKIM signatures. Perhaps it's something to look at? Most lists I'm on manage to pass messages with DKIM intact. Authentication-Results: abc.abc.abc; dkim=fail (rsa verify failed) header.d=mrstuudio.ee header.s=mr header.b=M03Fp5lE; dmarc=pass (policy=none) header.from=dovecot.org; spf=pass Thanks, Reio -------------- next

Okay, Yahoo is bumming me. Only system my mail is having an issue with. All mail is accepted, but junked. I can only think it is the DKIM/Domain keys. It is apparent that the dkim-milter is not part of the centos 5.x distro nor is it part of the mirrors, as far as I can tell. So...have any of you done it with your servers for sendmail? There are some sites that claim to have rpms and I have
